Default Trim adjustments

Under the calculations trace window, fuel trim, there is an Other Enrichment window. I disabled coolant low map and coolant high map so that there were no more adjustments made there, I also disabled transient throttle. Yet the other enrichments window oscillates between 1-10% trim.
This is destroying my ability to tune the cars idle and many other things.

Have you guys had any issues with corrupt firmware or flashes that could cause this?

I'm also had another issue today. I was sitting at a stop sign idling and i turned off map based throttle enrichment and soon as I did the idle started oscillating like crazy. So I checked the box again to back the way it was. It kept oscillating for no reason.

I had a similar issue with trim intermittenly being added. Not sure why but it goes away when I use the Map Prediction Mode for transient tuning.
